Brembo 1BD.8032A2 GT Series Big Brake Kit with Drilled 2-Piece Rotors

The Brembo 1BD.8032A2 is a GT Series Big Brake Kit (BBK) engineered to deliver a dramatic upgrade over factory braking systems for performance street and track-day use. Built on decades of motorsport expertise, this complete kit replaces your OEM brake corner with larger-diameter components designed for superior heat management, pedal feel, and fade resistance.

At the core of the system are lightweight 2-piece floating brake discs with a cross-drilled finish. The cast iron rotor ring is manufactured from Brembo's proprietary iron alloy for extended service life, and is attached to a precision-milled billet aluminum hat using Brembo's floating "bobbin" hardware — allowing the disc to expand and contract thermally in both the radial and axial directions without warping or cracking. Vented construction and zinc coating add cooling efficiency and corrosion resistance.

Key Features:

• Brembo GT Series Big Brake Kit — complete front brake upgrade
• 2-piece floating rotor design with cross-drilled disc surface for heat dissipation and pad surface refresh
• Proprietary cast iron alloy rotor ring with billet aluminum hat and floating bobbin hardware
• Fixed, multi-piston aluminum alloy calipers for rigid clamping force on both sides of the rotor simultaneously
• Sequentially sized opposing pistons for even brake pad wear
• Quick-release pad retaining system with anti-rattle feature for easy pad changes
• Proprietary high-performance brake pad compound selected for the specific application
• Braided stainless steel brake lines included
• CNC-machined billet caliper mounting brackets, anodized for durability
• Fully compatible with factory master cylinder, ABS, and traction control systems
• All necessary hardware included for installation

The Brembo GT Series BBK delivers immediate, decisive braking response with consistent performance that holds up under repeated hard stops — whether on a twisty back road or a dedicated track session. The aluminum caliper construction saves significant weight versus OEM sliding calipers while providing a far stiffer, more responsive pedal. Calipers are available in bold Brembo signature colors, adding unmistakable visual impact behind open-spoke wheels.
